[Q]: Passage: As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10°. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92 mm (.312 in) MG 15 machine gun for the rear seat was added to the third prototype.

[Q]: Passage: Barton Stone Alexander (September 4, 1819 – December 15, 1878) was a Union Army lieutenant colonel, engineer regiment commander and chief engineer for the defenses of Washington during the American Civil War. In recognition of his service, in 1866, he was appointed to the brevet rank of brigadier general in the regular army, to rank from March 13, 1865. He was a graduate of the U.S. Military Academy at West Point and served in the United States Army's Corps of Topographical Engineers, which at times was both a part of and separate from the United States Army Corps of Engineers. After graduating from West Point as a second lieutenant in the Class of 1842, he served in the Mexican–American War, building fortifications to protect American supply lines in the advance on Mexico City. After the end of the war, he was stationed in Washington, D.C., where he served as architect for the Scott Building and Quarters Buildings at the U.S. Soldiers' Home and took over the completion of the Smithsonian Institution Building after dissatisfaction with the pace of the first architect caused him to be dismissed.

[Q]: Passage: Brown was born in 1937 in Lewes, Sussex, one of six brothers who all played football; two, Irvin and Stan, also played in the Football League. He played local football for Lewes St Mary's and Portslade before being called up for National Service. A tall, heavily built man, Brown was serving in Gibraltar in March 1958 when he was recommended to Brighton & Hove Albion as a promising centre half; he signed for the club six months later, the day after his brother Irvin, also a centre half, left it. He made his first-team debut three years later, by which time he had converted to play at centre forward, and made eight appearances, scoring twice, in the first half of the 1961–62 Second Division season. In January 1962, he joined Exeter City, managed by former Brighton team-mate Glen Wilson. He scored three goals from eleven Division Four appearances, and left at the end of the season for non-league football with clubs including Hastings United and Dover. After football, Brown worked as a landscape gardener. He died in Lewes in 2016 at the age of 78.
